II. GETTING STARTED
II.1 Autozero
Before readings may be taken, the Viscometer must be Autozeroed. This action is performed each
time the power switch is turned on. (Note: If cable DVP-80 is connected for printer or computer
communication see section II.9). The display window on the Viscometer will guide you through
the procedure as follows:
Turn the power switch (located on the rear panel) to the ON position. This will result in the screen
display shown in Figure II-1 indicating that the DV-II+Pro viscometer is in the standalone mode
(is not connected to a computer).

(the built in program which controls the instrument) and an alphanumeric code, which indicates
the Model number (see Table D-2 in Appendix D; the code indicates the spring torque rating or
the viscosity measurement range of your viscometer). For most DV-II+Pro Viscometers, this
information will be either “LV”, “RV” or “HB”:
